Figure 16 shows parts illustrated in Figures 14 and '15 assembled together and to a fastener carryingmeans.

Referring now more particularly to the form of machine illustrated in Figures 1-7 inclusive, wherein the features and principles of this invention are shown applied to a so-called foot press and adapted to assemble fastener parts together and to a fastener carrying means, a supporting base plate, or tray, H seated on suitable legs l2 has a vertically disposed standard l3 mounted thereon upon a die block 14, suitably secured to a plate H. The block l4 supports a die 15 in alignment-with a punch 16, slidably mounted in an enlarged front edge portion [1 of the standard 13, which portion l1 extends forwardlyto overhang the die Hi. The punch I6, in'this instance, is constituted by an elongated rod having its upper end 18 connected, as by a link Hi, to a treadle lever 2!. The treadle lever 2| is pivoted, on a pin 22, to and between lugs 23 and 24, suitably fastened to the standard l3, and extends downwardly inback of the base plate ing rearwardly from the base plate I l.

H and then forwardly below the plate its lower end 25 having a foot pad 26 thereon, whereby the lever 2| may be actuated by the foot of the operator.

A hopper 21 of suitable construction to contain, in this instance, fastener parts and feed them to a chute 28, is rotatably mounted on the standard l3 and is adapted to be rotated by a belt 29 through a pulley 3| connected to the hopper 21 by a shaft 32 in the usual and wellknown manner. The belt 29 is led over idler pulleys 33 and 34 and to, and over, a pulley 35 mounted on a shaft 36 jouraled in a bracket 31 depending from beneath the'base plate A ratchet wheel 33 secured upon the shaft "35 is adapted to be intermittently rotated by a pawl 33,

pivoted at ii (see Figure 2) to one end of a lever 42 rockably supported on the shaft 33. spring 43 secured to the lever 42 is provided, to maintain the paWl 33 in engagement with the ratchet Wheel 38. The other end of the lever 42 is pivotally connected to one end of a link 44 by a pin 45. The other end ofthe link 44 is pivotally connected to the treadle lever 2| by a pin 43. Rocking movement of the treadle lever 2| rearwardly, by the operator, will rock the lever ell-and, through the pawl 39 and ratchet wheel 33, cause the shaft 35 to be rotated. This rotation of the shaft 33 will, through the pulley 35, belt 23 and pulley 3|, cause the hopper 21 to be rotated to feed fastener parts therefrom into the chute 28 in the usual manner.

To, avoid possible undesired short movements of the pawl 33 on the ratchet wheel 38, due to possible subsequent swinging movements of the treadle lever 2| after being actuated by the foot of the operator, a friction device is provided to act upon the shaft 33. The friction device illustrated includes, a pair of opposing members 41 and 43 (see Figure 2), the upper ends of which are adapted to embrace a stud 49 extending from the bracket 31 and to be clamped thereto by a screw 5|. The lower ends of the friction applying members 41 and 48 embrace the shaft 36 and are urged into frictional engagement therewith by a spring 52 reacting between the head of a screw 53, screw-threaded into the member at, and the member 41. Should a jam of fastener parts occur in the hopper 21, or other interference occur preventing its rotation, the belt 2%! will slip on the pulley 3|, or the pulley 35 will slip under the belt 29, or both, to prevent any possible damage. The pulleys 33 and 34 (see Figure 2) are mounted on a stud shaft 54 secured in an arm 55, in turnadjustably secured, as by screws 56, to a bracket 51 extend- Adjustment of the arm 55 on the bracket 51 will vary the tension of the belt 29 and its frictional engagement on the pulleys 3|, 33, 34, and 35, and thus determine the point at which the belt 29 will slip thereon.

The improved means for transferring parts such as the fastener parts shown herein from the chute 28 to a position between the assembling means, herein constituted by the die |5 and-the punch Hi, includes an arm 6| and an arm 62, the latter one, 52, being superposed upon the arm iii. The arms 6| and 62 are pivotally secured upon a post 53 extending upwardly from the die block M by a nut 64, the post 63 constituting a common pivot for the arms BI and Hand being disposed a substantial amount to one side and back of the aligned vertical center lines of the punch and di l5 and I5 respectively. The arms 6| and 62 are swingable, relatively to each other, upon the post 63 and extend across and in back of, the punch l5 and die l5, to dispose their free ends 65 and 66, respectively, closely adjacent to the lower, and delivery, end 61, of the chute 23. The arms 6| and 62' are resiliently connected together for simultaneous swinging movement by a spring 68.

The spring 68 is secured, at one of its ends, to the arm 6| by a screw 59, then wrapped at least once about a spacing sleeve 1| formed as a part of the arm 6| and surrounding the post 33, and then has its other end extended and hooked about a pin 12 extending downwardly through the arm 6| from the arm 62 to which said pin 12 is secured. The pin 12 extends through an arcuately elongated slot 13 (see Figure 4) formed in the arm 6| and provided to permit the aforesaid relative movement between the arms iii and 32. An adjusting screw and nut 14 combination is provided, whereby the arms 5| and 52 may be adjusted relatively to each other.

The chute 28, in this instance, is adapted to guide fastener parts 15 (see Figure 9) moved from the hopper 21 to the lower armfil by gravity, and is provided with an inverted T- slot 13 for this purpose, the base 11 of the fastener part being guided by the larger-in-width slot portion and the stud portion 18 of the fastener part being guided by the smaller-in-width slot portion. The free end 35 of the arm 6| (see Figure 4) is shouldered back from its extreme end to provide a stop shoulder 19 against which the fastener parts may engage, to prevent them dropping from the chute 28 when the arm 6| is swung away therefrom, the end 65 and the shoulder 19 being extended arcuately and rearwardly for this purpose. The arm 6|, at its portion adjacent the end of the slot 16 in the chute 28, is provided, in this instance, with a fastener part receiving depression 8| from which an inverted T-slot 82 arcuately extends toward the front of the arm 6|, a plate 83 secured to the arm 6|, in this instance, forming a part of said T-slot. A tongue 84, formed on the plate 83, overlies the lower end 51 of the chute 28, and an extension thereof forms the opposite part of said T-slot. The tongue 84 guides the fastener part toward the depression Bl, the base 1'1 of the fastener part passingunder the tongue 84. The depression 8| with the T-slot 82 forms, what may be termed, a continuation of a T-slot 15 in the chute 28, and which is disposed sub stantially at right angles thereto. The end face of the shoulder 19 may be grooved, as at 85, if desired, to form a track for the base 11 of the fastener part to assist in 'maintaining it in proper position to feed to the depression 8| in the arm 6|. The post 63 is so positioned that when the arm 6| is swung thereabout (see Fig-- ure 7) the center line of the T-slot 82 will align with an arc struck through the vertical center axis of the die i5 with the axis of the post 63 as its center. Thus, when so swung, the arm E| will engage against the die |5 on an arcuately cut-away surface 86 in the arm 6|, the arm 6| at the bottom of the T-slot 82 being disposed substantially in horizontal alignment with the top surface of said die l5 so that fastener parts may be slid along from the T-slot 82 in the arm 6| and will drop onto the die IS in alignment with the punch It.

The means for sliding the parts to be assembled, such as the fastener parts shown from the on the arm 62 and a T-slot -82 in'the arm 6| onto the die I5 (see Figures 6 and 7) is constituted by the arm 62. arm -62, at its free end 66, is provided with a forwardly directed finger 81 which is aligned with the T-slot 82 and has a cross-slot 88 formed in its under-surface. The cross-slot 88 is so positioned thatwhen the free ends 65 and 66 of the arms BI and 62 ,and the arm 62 is moved relatively to the arms 6| toward the die I5 (see dotted lines in Figure 7).

posit a part on the die I5 semhled, for instance forwardmovement into its-normal positionof rest. The forwardly directed shoulder I03 is provided to insure rearward movement of the slide 93 should the spring I06 break, or become too weak to properly return the slide 93 into its rearward position and remove the arms 6| and 62 from over the die l5 and from in under the punch I6. An extension I68, provided on the arm-6| and adapted to engage the lower end 61 of the chute 28 limits the rearward swinging movement of the arms BI and 62 and, through the arm 62 and the link 94, the rearward sliding movementof-theslide'93. A coiled spring I09, reacting between apin II I on the bar 92 and a pin I I2 on the'treadlelever 2|, constantly urges the bar 92 downwardly in shoulder engaging position.

The operation of the above describedmachine is believed obvious from the above, and briefly is as follows. An operator presses the treadle lever 2| rearwardly whereby the lug Ill and the bar 92 will drop behind the shoulder Hi2 and lets the lever 2| swing forwardly to move the slide 93 forwardly. This forward movement of the slide 93 swings'the arms 6| and62 to deposit a part, such as the fastener part shown in'Figure 9, upon the die I5, the arm 62 being pushed by the slide 93 and the arm6| following due to its resilient connection through the spring 68 and the pin "with the arm fi'l. When the arm'BI engages the die I5 and the swinging movement thereof is'stopped, the arm 62 continues tomove to carry, in this instance, the fastener part 15 from the arm 6| to the die I5. 'When the fastener part I5 hasbeen carried'to a position directly over the die |5,the arm 62 is stopped, due'to the aforesaid engagement of the pin "12 with the forward end of the slot 73 in the arm 6| (as indicated in dotted lines in Figure 7), and the fastener part will then be disposed on the die I5 in line with the punch i 6. As this action takes place the end I05 of the arm' 92 rides up over the plate I 04 andthe slide is free to'be returned by the spring I 66. A fastener receiving means, such as a strip of material M3, (see Figure 10) which has suitable fastener partreceiving holes punched therein, is laid overthe die |5 and part "I5 to allow the stud '18 of the fastener part to pretrude upwardly therefrom. A fastener part IM (see by the operator over thestud l8 and the treadle lever 2| is again pressed rearwardly to force the punch against the fastener partI I4, audit in turn downwardly over the stud'm, which is forced into the part I I4 and tightly criinped therein to secure the fastener partstogether and to the strip of material I! 3 The strip H3 is now removed from the die I5. As the-treadle leverZI was pressed rearwardly to assemble the parts, the hopper'if'l-was rotated, and as the lever 2| again swings forwardly the arms'fil and fii again deprovided no interference is sustained, such as, for instance, the failure of the-operator to remove the stripII's die'I 5. Should such interference exist matically returnto their partreceiving position due tothe'action of the spring'ldt on the pin 72 and on the arm 62, which through the linkfi l returns the slide "93.

"Whenit'is-desired to feed" both partsto be asfastener parts such as .shownflin Figures .14 and '15,"two. hoppers maybe 32, one on either side of the standard I3. In such instances two chutes I2I and I22 are provided, one leading from one of the hoppers and directed toward a pair of arms I23 and I24, and the other leading from the other hopper and directed toward another pair of arms I25 and I26. The pairs of arms I23, I24, and I25, I23 are arranged one above the other as indicated in Figure 11, and are pivoted one pair, I23, I24, on a post I21 suspended from a standard I28 and the other pair, I25, I23, on a post I20 mounted on a die block similar to I4 in Figure 1. Two sets of bars and slides, not shown, but each similar in every respect to those shown in Figures 1, 2, and 3, are provided, one for actuating each pair of arms I23, I24, and I25, I25.

The upper pair of arms I23, I24 operate the same as the previously described arms and I52 but are reversely formed to swing from an opposite side of the standard I3 to deposit a part such as the fastener part I30 (see Figure 14) onto a depressed surface I3I formed in the lower ends of a pair of opposing jaws I32 and I33 pivoted to a ring I34 fastened to the standard I28. The jaws I32 and I33 are constantly urged together by a coiled spring I35 and preferably engage against the lower end of a punch I33. In this instance the swinging movement of the lower arm I23 causes it to engage the jaws I32, I33 to be stopped thereby while the arm I24 moves the fastener part I30 from the arm I23 onto the depressed surface I3I of the jaws I32, I33. When descending, the punch I36 engages the fastener part I30, opens the jaws I32, I33, and carries it downwardly toward the die I31. In order that the fastener part I30 will not drop from the end of the punch I33, the latter is provided with means to retain the fastener part I30 thereto and this means is constituted by a spring tensioned wire finger I38 (Figure 13) which extends into a bore I39 formed in the end of the punch I33, and engages an annular groove I4I formed in the stud portion of the fastener part I30. The material of the finger I38 extends upwardly in a groove I42 and is crimped over on the opposite side of the punch to secure it thereto.

The arms I25, I23, in this instance (see Figure serve to carry a fastener part I43 to be assembled to the part I30, said part I43 having a relatively long stud portion I44, and transfer it from the chute I22 to the die I31. In this instance the upper arm I25 is provided with a pivoted finger I45, acted upon by a leaf spring I43 to engage the stud I44 of the fastener part steady, in vertically disposed position between it and the arm I26, while it is being transferred. Both the arm I25 and the finger I45 are provided with arcuate grooves I41 and I48 respectively to embrace the stud portion I44. The die I31, in this instance, is provided with a slidable sleeve I49 which surrounds the die I31 and extends upwardly above the upper surface thereof to form a cup to receive the flange of and centralize the fastener part I43 when it is delivered thereto. The sleeve I43 is constantly urged upwardly by a coiled spring I5I reacting between the sleeve I49 and the die block I52, upon which the die I31 is mounted, and is limited in its sliding movements on the die I31 by a screw I53 cooperating with the die in an elongated slot I54 formed in the side thereof. The sleeve I43 is permitted to extend above the die I31 sufficiently to stop the arm I25 but not the arm I26 in their swinging movement and to receive the flange of provided on the shaft .the fastener part I43 and hold the part I43 therein while the finger I45 springs past the stud portion I44 of the part I43 when the arms I25 and I23 return to fastener-part receiving position.

As in the form shown in Figures l-7 inclusive, the operator first actuates the treadle lever to dispose the fastener parts to be assembled on the depressed surface of the jaws I32 and I33 and onto the die I31. A piece of material I55 (see Figure 16) is then placed over the stud I44 of the fastener part I43, so that it extends through a hole in the material I55, and then the treadle lever is actuated to cause the punch I36 to descend and assemble, the two fastener parts I30 and I43 together and to the material I55. When the lower arms I25, I26 return to part receiving position, as shown in Figure 12, the finger I45 engages against the lower end of the chute I22 and is swung away from the arm I23 to provide sufficient space between it and said arm for parts I43 to feed by gravity from the chute into the depression in the arm I25, as in the previously described form.

By the provision, in a machine of the above nature, of the swingable arms pivoted to the rear and to one side of the die, and of the chute ends which terminate to the rear and to one side of the die, fastener, or like, carrying means of various widths may have fasteners applied thereto without said means being interferred with, or engaging, any of the machine parts, the standard- I3 being considerably cut back below the lower end of the punch supporting portion thereof for this purpose. In view of the above described structure a machine for the purpose desired has been provided which is relatively simple in construction, of comparatively few parts, and is particularly efficient and durable in use. Due to the open arrangement of the various mechanisms in the machine of this invention, the parts thereof are readily accessible for changes, or repairs, and all of the movable parts, as well as the work, are plainly visible to the operator.

While there have been shown and described herein two forms of an improved assembling machine, it is to be understood that the invention may be embodied in other forms without departing from the spirit and essential attributes thereof. It is therefore desired that the present embodiments be considered in all respects as illustrative and not restrictive, and it will be further understood that each and every novel feature and combination thereof, present in, or possessed by, the mechanism herein disclosed, forms a part of the invention included in this application.
